How To: Harla'Dar

At First Glance

She's a unique dragon. The lore for most of the dragons in EQ suggests that the dragons are hermits. They will keep servants in their layer. However they keep their personal chambers free of other living things. Harla'Dar has surrounded herself with a lot of strong servants. She will call them to aid her if she is threatened.

The prefight

You're probably saying "Holy hell.. we can't take on all those adds at once" And you're right. You were never supposed to fight all those adds and Harla'Dar at the same time. What you want to do is clear the instance of adds then fight Harla. But wait! Before you start going willy nilly on the mobs, the mobs respawn. And some respawn faster than others. Here's the order in which you want to kill these mobs.

Lizards
Drakotas on the lower floor
Droags
Drakotas on the upper floor.

The best way to do this, Pull a lizard, get it down to 10% health, tell everyone to stop attacking and pull another lizard. Keep doing this until your raid force can't handle any more adds (usually 6 lizards). Now, you're probably thinking "We don't have enough power to do this" Well, you do. If you yell. That's right. Yell every encounter you start with the exception of Harla'Dar. Now, once you have as many mobs as you can handle, burn them all down fast. And watch the clock. Announce to the raid when the first mob dies. Those mobs will respawn a half hour later.

The Main Event

It's that time. The best way to fight Harla'Dar is .. Have your raid force on the bottom floor, near the doors. Send your uber monk tank to the top. Have him do a Tsunami pull and jump down to your raid. From there you just need to burn her down as fast as possible. If you were fast enough you'll have 0 adds to deal with.

Make sure your cold and magic resists are as high as possible. You'll need someone who can group cure both in each raid group.
